Abstract: The disclosure relates to cryoablation probe assemblies including a cryoablation probe and sheath configured to accelerate thawing of the probe from frozen, treated tissue. The sheath can include a plurality of channels configured to direct saline or other biocompatible fluid to the treated tissue. The sheath is configured to slide and advance distally over the cryoablation probe to continually thaw the tissue until the cryoablation probe is freed. Methods of treating atrial fibrillation with a cryoablation probe assembly are also disclosed.
